Answer:
The music was played at an natural frequency of the drums
Explanation:
The natural frequency of a body is the frequency when we notice that the system oscillates without any driving or damping force. This is also referred to as the normal mode of vibration because all parts of the system move sinusoidally at the same frequency.
So, when music is played at the natural frequency of the drums, the drums tends to vibrate without any driving force. We can now say that the drums are 'playing themselves'.
Answer:
Cu(NO₃)₂ + 2NaOH → Cu(OH)₂ + 2NaNO₃
Explanation:
This is the reaction:
Cu(NO₃)₂ + 2NaOH → Cu(OH)₂ + 2NaNO₃
Let's verify the ions charges
Cu(NO₃)₂ → Cu²⁺ + 2NO₃⁻
NaOH → Na⁺ + OH⁻
Cu(OH)₂ → Cu²⁺ + 2OH⁻
NaNO₃ → Na⁺ + NO₃⁻
Explanation:
There are two aspects of a reaction:
Thermodynamics:
Combustion of the compound is reaction with oxygen.
The carbohydrates contain more content of oxygen as compared to fats.
Hence, carbohydrates have lot of oxygen content which are already partially oxidized as compared to fats. Hence, combustion of the carbohydrates is a faster process.
Kinetics:
The molecular reacts also shows that the combustion of the carbohydrates is a faster process.
